I'm trying to migrate webpack4 to webpack5. My project has both react and typescript files.
I'm running into below error:
ERROR in ./src/index.js 19:4
Module parse failed: Unexpected token (19:4)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
>ReactDOM.render(
> > <Provider store={store}>
> | <App/>
